Material Requirements Planner (MRP)

A typical week often involves MRP run review, exception management, item master maintenance, and coordination with buyers and planners — analyzing MRP exception messages, adjusting safety stock or lead times that aren't reflecting reality, working with buyers on action messages, partnering with planners on production-schedule alignment. You're often the systems hand on the engine that drives buying and production decisions. MRP signal quality and exception-message clearance are the operating measures.

The harder part is often the garbage-in problem — MRP outputs are only as good as the master data behind them, and parameters drift away from reality faster than people maintain them. Variance across employers is wide: at mature manufacturers the role runs on SAP or Oracle with established governance; at growing companies you may be building MRP discipline as you go.

The work fits people who are analytical, comfortable with ERP systems, and patient with data-cleanup work. APICS CPIM and ERP-specific training anchor advancement. The trade-off is the invisibility of MRP planning — when the system runs well, no one notices; when it doesn't, materials and operations both come asking why.
